[0002] In ultra-high pressure fluid system operation scenarios, such as high-pressure wellhead testing in oil exploration and hydraulic testing in aerospace, the detection and protection of ultra-high pressure media are crucial. To ensure stable system operation, accurate acquisition of media parameters, and response to emergencies, specialized detection and protection devices are needed to comprehensively manage the on / off control, pressure monitoring, safety protection, and equipment maintenance convenience of ultra-high pressure media. These devices can achieve orderly transmission and regulation of media in ultra-high pressure environments, promptly intercept overpressure risks, and can also flexibly expand functions with the help of adaptable structures. They are of great significance in improving the safety, efficiency, and adaptability of ultra-high pressure operations and are a key support for the efficient and stable operation of ultra-high pressure fluid systems.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figures 1-10 One embodiment of this utility model is a detachable ultra-high voltage detection and protection device, comprising:

[0039] Protective valve 1 has a ball valve 2 installed on one side of its outer wall. The input end of ball valve 2 is threadedly connected to a threaded connector 3. An exhaust assembly is installed on the bottom outer wall of protective valve 1. The exhaust assembly can discharge the internal air before the device is started, so as to avoid the formation of air resistance during the transmission of ultra-high pressure medium, which would affect the stable flow of the medium and the detection accuracy. A connecting assembly is installed on the other side of the outer wall of protective valve 1. The connecting assembly expands the medium transmission path of the device and can meet the needs of medium diversion and reversal in different detection scenarios.

[0040] Flange 4 is fixedly connected to the outer wall of the protective valve 1 on the right side. A threaded through hole 14 is provided inside the left side of flange 4. The threaded connector 3 is threadedly connected inside the threaded through hole 14. A sealing groove is provided inside flange 4 to provide axial sealing.

[0041] Quick-connect fitting 5 is threaded to the output end of ball valve 2. One end of quick-connect fitting 5 has an external thread on its outer wall. Its male design allows it to quickly connect with the matching female fitting, realizing the rapid connection of the medium transmission path. Both ends of threaded fitting 3 have external threads G1 / 2. This symmetrical thread structure allows it to perfectly adapt to the internal threads of ball valve 2 and flange 4, serving as a bridge connecting the two.

[0042] The exhaust assembly includes a hose 6, which is installed on the bottom outer wall of the protective valve 1. One end of the hose 6 is threadedly connected to a threaded connector 2 7, and the other end is threadedly connected to a threaded connector 3 9. One end of the threaded connector 2 7 is provided with a flange plate 8, which has a threaded through hole 2 15 and a sealing groove for axial sealing. The threaded connector 2 7 is threaded into the threaded through hole 2 15. One end of the flange plate 8 is fixedly connected to the bottom outer wall of the protective valve 1. The connection assembly includes a tee connector 10, which is installed on... On the other side of the outer wall of the protective valve 1, one end of the tee joint 10 is threadedly connected to a threaded connector 4 11. One end of the threaded connector 4 11 is provided with a flange 2 12. The flange 2 12 is provided with a threaded through hole 3 16. The threaded connector 4 11 is threadedly connected to the inside of the threaded through hole 3 16. The other end of the tee joint 10 is provided with a ball valve 2 17. The input end of the ball valve 2 17 is threadedly connected to a threaded connector 5 13. The bottom end of the threaded connector 5 13 is threadedly connected to the inside of the tee joint 10. The tee joint 10 and the ball valve 2 17 are connected through the threaded connector 5 13.

[0043] All threaded connection dimensions mentioned above are G1 / 2.

[0044] Working principle: The ultra-high pressure medium first enters through the internal thread G1 / 2 on the left side of flange 4 and engages with the external thread G1 / 2 of threaded connector 3. The right side of threaded connector 3 then connects to the internal thread G1 / 2 on the left side of ball valve 2 to form the initial input channel. The right side of flange 4 has a sealing groove inside and fits with the end face of protective valve 1 through an axial seal to prevent axial leakage of the medium. Ball valve 2 controls the on / off state and flow rate of the medium entering protective valve 1. Protective valve 1 is the core control component, and the internal valve core adjusts the pressure or on / off state according to the system requirements.

[0045] The exhaust assembly expels internal air during startup. The specific exhaust path is as follows: the external threads G1 / 2 at both ends of threaded connector 2 7 engage with the internal threads G1 / 2 at the bottom of protective valve 1 and the left internal thread G1 / 2 on flange plate 8, respectively. The sealing groove on the right side of flange plate 8 provides axial sealing. The internal threads G1 / 2 at both ends of hose 6 connect threaded connector 2 7 and threaded connector 3 9. After air is exhausted through this path, the passage can be closed. During media output, the internal thread G1 / 2 on the right side of ball valve 1 2 connects with the external thread G1 / 2 of quick-connect connector 5. Quick-connect connector 5 can quickly connect to the downstream female connector assembly, enabling flexible media transfer.

[0046] In the right-side connection assembly of protective valve 1, the internal thread G1 / 2 of tee fitting 10 is connected to the internal thread G1 / 2 of flange 2 12 through threaded fitting 4 11, expanding the branch passage. The internal threads G1 / 2 at both ends of ball valve 2 17 are adapted to the external threads G1 / 2 of threaded fitting 5 13, controlling the opening and closing of the branch passage. Each threaded connection is reinforced with sealant to enhance radial sealing. All components are detachably connected through G1 / 2 threads. When a component fails, the corresponding fitting can be quickly disassembled for replacement. After replacement, tightening can restore operation. This ensures mechanical strength and sealing performance under ultra-high pressure environment, while also meeting the flexibility requirements for testing and maintenance.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
